Aromatic solvent naphthas represent a cornerstone of modern industrial formulations, particularly in sectors requiring high boiling points, controlled evaporation rates, and high solvency power. These complex hydrocarbon mixtures—principally consisting of C9 to C12 alkylbenzenes, naphthalenes, and associated polycyclic aromatics—are vital for agricultural formulation stability, heavy-duty protective coatings, and precision chemical synthesis.
As regulatory agencies worldwide impose stricter thresholds on volatile organic compounds (VOCs) and hazardous air pollutants (HAPs), the demand for specialized, naphthalene-depleted (ND) formulations has reached unprecedented heights. Industry experts and formulation chemists must now balance solvent efficacy with environmental compliance, driving chemical plants to implement sophisticated refining technologies such as multi-stage continuous vacuum distillation and catalytic hydrodearomatization.
"The shift toward low-naphthalene options (ND grades) is not merely a compliance trend; it is a critical optimization variable that prevents phytotoxicity in crop protection products and reduces exposure risks in industrial paint application."
Under the corporate governance of Shandong Saier Chemical Technology Development Co., Ltd., our manufacturing site in Zibo's Qilu Chemical Industrial Park operates at a design capacity of 720,000 metric tons per annum. By integrating raw material feeds directly from Sinopec, PetroChina, ChemChina, Zhejiang Petrochemical, and Hengli Petrochemical, our distillation trains maintain operational consistency year-round.
Our OEM capabilities extend beyond simple bulk refining. We partner with formulation scientists globally to customize distillation profiles, modify flashpoints, and isolate specific isomers (such as Durene/1,2,4,5-Tetramethylbenzene) to serve as precursors for polyimide films and specialized electronic resins.
A technical breakdown of our main aromatic hydrocarbon grades, designed to match the evaporation kinetics and Kauri-Butanol (KB) index requirements of global formulators.
CAS No.: 64742-95-6
Composed primarily of C9 aromatics. Characterized by an initial boiling point of >150°C, a flash point of >40°C, and rapid evaporation profile relative to higher-boiling analogs. Highly compatible with alkyd resins, acrylics, and agricultural emulsifiers.
CAS No.: 64742-94-5
A C10-heavy distillation cut featuring an initial boiling point of >178°C and a flash point of >62°C. Excellent paint leveling, high solvency power, and robust solvency matrix suitable for agricultural EC formulations and industrial coatings.
Naphthalene Depleted (<1% or <0.1%)
Manufactured via advanced crystallization and narrow-fractionation to deplete the naphthalene content below 0.9% by weight, mitigating phytotoxicity risk and complying with stringent European and North American HAP limitations.
High Boiling Hydrocarbon Cut
Designed for specialized industrial baking enamels and slow-cure adhesive systems. Features a boiling range between 200°C and 250°C, providing exceptional wetting characteristics and long open times.
CAS No.: 64742-94-5 (C11-C12+)
Boiling point range of 220°C to 290°C. Flash point >100°C makes S200 extremely safe from an operational handling perspective. Commonly deployed in heavy-duty oilfield chemicals, anti-corrosive marine paints, and high-boiling pesticide formulations.
CAS No.: 95-93-2
A high-purity crystalline intermediate sourced from specialized aromatic distillation cuts. Essential for the synthesis of Pyromellitic Dianhydride (PMDA), which is the principal precursor for manufacturing high-performance Polyimide films (Kapton-equivalent).

How our aromatic hydrocarbons are integrated into major global value chains, ensuring product shelf-life, application precision, and safety.
In the crop protection industry, emulsifiable concentrates (ECs) require solvents that exhibit extreme solubility for active ingredients (fungicides, herbicides, insecticides) while preventing crystallization at sub-zero storage temperatures. Our S150ND and S200 grades are tailored to minimize crop phytotoxicity (leaf scorch) and maintain emulsion stability upon dilution with hard water.
Industrial paints, marine coatings, and automotive primers require solvents with optimized evaporation curves to facilitate proper film formation and leveling. By employing S100 and S150 as tail solvents, manufacturers can eliminate pinholing, surface defects, and blistering while ensuring excellent adhesion of resins to metallic and composite substrates.
Our Heat Transfer Oil L-QC320 and related heavy aromatic fractions provide exceptional thermal stability up to 320°C in closed-loop systems. In oilfield service applications, our high-boiling aromatic solvent naphthas function as pour-point depressants, drag reducers, and paraffin wax dispersants under harsh downhole conditions.
